been taken to keep the arcade, triforium, and clerestory exactly on the same level. There could be no motive for doing otherwise. I take the case to be this. The three bays were added, as such additions often were, without any regard to the style or proportion of the original building, beyond keeping the walls themselves at the same height. In an addition, like the presbytery, built in an utterly different style and without any adaptation to the earlier work, it was of no great moment whether the three divisions of the elevation exactly agreed or not with the levels of the older work. But a little later, probably when the roof came to be added, the idea suggested itself of bringing the three older bays into harmony, as far as might be, with the newer ones. The roofing of the presbytery would naturally suggest this change; it would perhaps make it absolutely necessary. For the form of roof chosen for the new work was of a kind very different from the older vaults of the church, and of a kind very singular and unusual. It is in fact a coved roof, such as we are used to in woodwork in this part of England, only with cells cut in it for the clerestory windows.[9] Such a roof could hardly have been added to the three eastern bays without disturbing the original roof of the three western bays; and it could hardly have been, as it was, carried over the three western bays also without disturbing the original triforium and clerestory. When therefore the design of the roof of the presbytery was determined on, the attempt was made to adapt the triforium and clerestory of the choir to those of the new work. But it was now impossible to keep the exact levels, and the result is what we see. You will remark that the upper stages of the choir were not, strictly speaking, rebuilt, but were simply cased and new windows inserted. The latter process, as is to be seen on the outside, was somewhat awkwardly done. The aisles of the choir were also recast at the same time by the addition of a vault and the insertion of windows in the new style.
